[0048] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0049] For patients who are bedridden for a long time, staying in the same position for a long time will cause ischemia in the compressed parts of the patients, leading to adverse events such as pressure ulcers. It is necessary to turn the patients over to the side to change the body position; in addition, when performing medical operations such as dressing changes on the local injuries of the patients and turning the patients over to maintain the body position, manual turning over and maintaining the body position are inconvenient, time-consuming and laborious, and the maintained body position is unstable.

[0050] The present utility model relates to a flip-type support mattress for assisting patients to turn over and maintain the turned-over body position. One end of the support flap 3 is rotatably connected to the bottom plate 1 and can be rotated to abut against and support the patient after rotation. The top end of the support rod 4 is rotatably connected to the support flap 3 to form a triangular structure with the bottom plate 1 and support the support flap 3. The bottom end of the support rod 4 is slidably fixed on the rotating rod 2 to adjust the flipping angle of the support flap 3. The adjusting mechanism can adjust the rotation of the rotating rod 2, so as to drive the limiting component fixed on the rotating rod 2 to rotate synchronously. When the limiting component faces the support rod 4, it limits the bottom end of the support rod 4 to fix the flipping angle of the support flap 3. After the rotating rod 2 rotates, the limiting component rotates synchronously, and the bottom end of the support rod 4 can slide bidirectionally in the installation groove 11 to realize the retraction and extension of the support flap 3; it can solve the problem that it is inconvenient for patients to turn over to the side and maintain the body position.

[0051] A flip-type support mattress, specifically, as Figures 1 to 7When the cam 2 is in the upright position, the cam 2 is in the upright position, and the cam 2 is in the upright position, so that the cam 2 can move freely, and the cam 2 can move freely, and the cam 2 can move freely. One end of the support flap 3 is rotatably mounted on the base plate 1, and is supported and fixed by the support rod 4 when it is rotated to the position where it needs to be fixed; the adjustment mechanism can drive the rotating rod 2 to rotate around the axis, thereby driving the limit assembly thereon to rotate, and when the limit assembly is adjusted toward the support rod 4, the bottom end of the support rod 4 can be limited, thereby adjusting the sliding of the bottom end of the support rod 4 on the rotating rod 2, thereby adjusting the rotation angle of the support flap 3, and adapting to the side-turning position of the patient at different angles of the abutment support.

[0052] In one embodiment, an adjustment mechanism is described, such as Figure 1 and Figure 3 As shown, the adjustment mechanism includes a drive member, which is in transmission connection with the rotating rod 2 and is used to drive the rotating rod 2 to rotate. In one embodiment, a knob 5 that can rotate about its own axis is selected as the drive member. The knob 5 is in transmission connection with the rotating rod 2 to drive the rotating rod 2 to rotate. Using the knob 5 as the adjustment mechanism has a simple structure. Turning the knob 5 can drive the rotating rod 2 to rotate, making it easy to operate. During use, when the support flap 3 is supported and fixed, the limit assembly is positioned in the direction from the rotating rod 2 to the support rod 4. The bottom end of the support rod 4 is restrained by the limit assembly. When the knob 5 is turned, the limit assembly rotates accordingly to release the restraint on the bottom end of the support rod 4.

[0053] Based on the fact that the adjustment mechanism includes the knob 5, in a certain embodiment, as Figures 1 to 3 As shown, the adjustment mechanism also includes an anti-rotation mechanism provided on the base plate 1 for preventing the knob 5 from rotating; a mounting hole is provided on the base plate 1, one end of the knob 5 is provided in the mounting hole, a driving tooth 51 is provided on the end face or circumferential side of the knob 5, and a driven tooth 21 is provided on the end face of the rotating rod 2 to engage with the driving tooth 51; the driven tooth 21 can be provided on the circumferential side of the rotating rod 2; the knob 5 can be provided on the top surface of the base plate 1 or on the side surface of the base plate 1. When the knob 5 is provided on the top surface of the base plate 1, the rotation axis is in the vertical direction (such as Figure 3When the knob 5 is arranged on the side of the base plate 1, the rotation axis is in the horizontal direction. The knob 5 and the rotating rod 2 are connected by the driving teeth 51 and the driven teeth 21 that are engaged with each other. The structure is simple and easy to implement.

[0054] Based on the adjustment mechanism including the anti-rotation mechanism, such as Figures 6 to 7 As shown, the anti-rotation mechanism includes an anti-rotation slot 14 provided on the base plate 1, a fixed pin 6 axially slidably disposed within the anti-rotation slot 14, and an elastic member 7 with its ends abutting the anti-rotation slot 14 and the fixed pin 6, respectively. The elastic member 7 can be a spring, which generates a thrust on the fixed pin 6. The fixed pin 6 is fixed with a shift block 62 and a latching protrusion 61 at the end away from the elastic member 7. The knob is provided with a latching groove 52 on the circumferential side surface, which engages with the latching protrusion 61. Under the thrust of the spring, the latching protrusion 61 of the fixed pin 6 engages with the latching groove 52, preventing the knob from rotating.

[0055] Based on the anti-rotation mechanism including the fixing pin 6 and the anti-rotation slide groove 14, as shown in FIG. Figure 6 As shown, the engaging protrusion 61 is a first engaging tooth; a second engaging tooth is provided on the outer side of the knob circumference to engage with the first engaging tooth, and the gap between adjacent second engaging teeth forms the engaging groove 52.

[0056] Based on the anti-rotation mechanism including the fixing pin 6 and the anti-rotation slide groove 14, as shown in FIG. Figures 6 to 7 As shown, a limiting groove 15 with an open top is extended from the side wall of the anti-rotation slide groove 14, and the shift block 62 can be embedded in the limiting groove 15 after the fixing pin 6 rotates around the axis.

[0057] Based on the fact that the adjustment mechanism includes a knob 5, a positioning mark is provided on the knob 5; an indicator mark is provided on the base plate 1, and the indicator mark includes a first indicator position and a second indicator position. When the positioning mark corresponds to the first indicator position, the limit assembly limits the position of the support rod 4; when the positioning mark corresponds to the second indicator position, the limit assembly does not limit the position of the support rod 4. The positioning mark and the indicator mark facilitate the operator to adjust the knob 5 to the desired functional position, making it easier to use.

[0058] In one embodiment, if Figures 3 to 4 As shown, the limit assembly includes multiple limit blocks 22 fixed to the rotating rod 2 at intervals. The multiple limit blocks 22 are fixed to the rotating rod 2 at intervals and located on the same side of the rotating rod 2. The limit blocks 22 are spaced apart on the surface of the fixed rod to form multiple gears for fixing the rotation angle of the support flap 3. By adjusting the position of the bottom end of the support rod 4, the support flap 3 can be fixed at multiple rotation angles, providing multiple side tilt angles for the patient and greater versatility.

[0059] Based on the fact that the limiting assembly includes a plurality of limiting blocks 22, in a certain embodiment, as Figures 3 to 4As shown, the limiting block 22 is wedge-shaped. One end of the limiting block 22 close to the connection bottom plate 1 of the support flap 3 is smoothly adhered to the surface of the rotating rod 2, and the other end protrudes from the surface of the rotating rod 2, and its end face can unidirectionally limit the end of the support rod 4, that is, it can move from the smooth end to the protruding end, and the reverse movement makes the end face of the protruding end abut against the limit. The limiting block 22 is wedge-shaped. When the support flap 3 is opened, the bottom end of the support rod 4 slides on the rotating rod 2. One end of the wedge-shaped limiting block 22 is adhered to the surface of the rotating rod 2, which is convenient for the bottom end of the support rod 4 to slide unidirectionally on the rotating rod 2, and avoids both ends of the limiting block 22 protruding from the surface of the rotating rod 2, which is not convenient for the bottom end of the support rod 4 to slide. The orientation of the smooth end of the wedge-shaped limiting block 22 does not necessarily point to the end connecting the bottom plate 1 of the support flap 3, and its smooth end orientation can be set reversely; when the limiting block 22 is on the right side of the vertical direction of the rotation axis of the support rod 4 (the support rod 4 forms an obtuse triangle with the support flap 3 and the bottom plate 1), the smooth end faces to the right, and the protruding end limits the rightward movement of the bottom end of the support rod 4; when the limiting block 22 is on the left side of the vertical direction of the rotation axis of the support rod 4, the smooth end faces to the left, and the protruding end limits the leftward movement of the bottom end of the support rod 4.

[0060] In some embodiments, such as Figure 4 As shown, the bottom of the support rod 4 is provided with a contact part that can slide and abut against the rotating rod 2; a guide slider 41 is fixedly provided on one side of the bottom end of the support rod 4 facing the side wall of the installation groove 11 and is located above the contact part, and the end of the guide slider 41 away from the support rod 4 slides and abuts against the side wall of the installation groove 11. Preferably, the guide slider 41 is fixedly provided protruding from both side walls of the installation groove 11 at the bottom end of the support rod 4, and the guide sliders 41 on both sides of the support rod 4 slide and abut against the side wall of the installation groove 11; the distance between the side wall of the installation groove 11 and the surface of the rotating rod 2 allows the limiting component to rotate a certain angle. By the guide slider 41 abutting against the side wall of the installation groove 11, the bottom end of the support rod 4 can slide along the axial direction of the rotating rod 2, and its guiding function avoids the situation of jamming and other unsmooth sliding caused by side deviation during the sliding of the support rod 4.

[0061] On the basis that the guide slider 41 is provided at the bottom end of the support rod 4, in a certain embodiment, such as Figure 4 As shown, a baffle 13 is provided on the bottom plate 1. The baffle 13 is located above the guide slider 41 and has a gap with the guide slider 41. Preferably, a guide chute 12 is provided extending from the side wall of the installation groove 11. The guide chute 12 is provided on the bottom plate 1 to form the above baffle 13, and the guide chute 12 is located below the baffle 13; the end of the guide slider 41 away from the support rod 4 slides and abuts against the side wall of the guide chute 12. The baffle 13 can limit the guide slider 41 vertically, and avoid the bottom end of the support rod 4 detaching from the bottom plate 1 during the movement; the gap between the baffle 13 and the guide slider 41 provides space for the bottom end of the support rod 4 to slide through the limiting component.

[0062] In some embodiments, such as Figure 1As shown in the figure, one end of the supporting flap 3 is hinged to the bottom plate 1; the above-mentioned support rods 4 are hinged on both sides of the supporting flap 3, and the bottom ends of the two support rods 4 are respectively provided with a rotating rod 2 and an adjusting mechanism. The two support rods 4 supporting the same supporting flap 3 can provide higher stability, so that the supporting flap 3 is not prone to tipping during rotation.

[0063] In some embodiments, as Figure 2 shown, the bottom plate 1 includes a first plate body 1a rotatably connected to the supporting flap 3 and a second plate body 1b connected to the first plate body 1a on one side of the supporting flap 3; the mounting groove 11, the rotating rod 2 and the adjusting mechanism are provided on the first plate body 1a corresponding to the supporting flap 3. The second plate body 1b can be used for vertically supporting and receiving the patient, avoiding displacement when the supporting flap 3 is turned up and forms a triangle with the first plate body 1a when the supporting flap 3 supports the patient. When the patient is supported by the supporting flap 3 on the second plate body 1b, the device will not move due to the supporting flap 3 being squeezed by the patient.

[0064] In some embodiments, as Figure 5 shown, two sets of flipping support components are provided on the bottom plate 1, and the two sets of flipping support components are arranged in a mirror symmetry; the facing sides of the supporting flaps 3 of the two sets of flipping support components are hinged to the bottom plate 1, so that both the left and right sides of the patient can be supported by the supporting flap 3 for position and body position, with higher versatility and practicability. Preferably, the flipping support mattress can be made of non-metallic material to be suitable for entering the X-ray, CT and MR examination cabins.

[0065] In a certain embodiment, as Figure 1 and Figure 5 shown, a supporting flap 3 and its corresponding support rod 4, mounting groove 11, rotating rod 2 and adjusting mechanism form a set of flipping units; multiple sets of flipping units are arranged side by side along the length direction of the bottom plate 1. The multiple flipping units are arranged side by side, and the supporting flap 3 that needs to be flipped can be selected to support the patient, and the supporting flap 3 of the part where medical operations need to be performed is laid flat to reserve an operation space for convenient use.

[0066] During actual use, place the flipping support mattress with two sets of flipping support components under the patient. According to the patient's need to turn over, select to open the supporting flap 3 of the flipping support component. The specific operation includes rotating the knob 5 to drive the rotating rod 2 to rotate through the driving tooth 51 and the driven tooth 21, so that the limiting block 22 faces the side of the support rod 4, opening the supporting flap 3 to the required angle, and the bottom end of the support rod 4 automatically gets stuck on the end face of the wedge-shaped limiting block 22, so that the support rod 4 generates a supporting effect on the supporting flap 3, and then the patient is supported by the supporting flap 3 in contact with the patient to achieve turning over and maintaining the patient's body position. When retracting and deploying the supporting flap 3, rotate the knob 5 to make the limiting block 22 rotate a certain angle along with the rotating rod 2. When the bottom end of the support rod 4 axially slides on the rotating rod 2, there is no blocking by the limiting block 22, and the supporting flap 3 can be retracted and put down.
